Description

Using an Array as a template literal gets this error:

Invalid type "string[]" of template literal expression. eslint[@typescript-eslint/restrict-template-expressions](https://typescript-eslint.io/rules/restrict-template-expressions)

the toString method when called returns a comma delimited string, which is pretty much what you would want. I don't see much unexpected there that would need a warning, so the reasoning behind erroring on other types does not hold for Array (and probably other Array types too)

Fail

Pass
